There are specific virulence factors that specific species of bacteria posses that make them pathogenic towards humans. There are waaaay to many to list on this website, but some examples are that some bacteria like Streptococcus pneumoniae possess a polysaccharide capsule that resists phagocytosis from white blood cells. Some like E. coli O157:H7 release toxins that can act on our nervous system, digestive system, etc. Many bacteria can create biofilms which are incredibly hard to get rid of and can wreak havoc on our bodies depending on where the film was formed. And the list goes on and on. Sometimes bacteria cause disease not because they're particularly invasive to humans, but because the human host has a compromised immune system. An example of this is someone with AIDS.
